Synopsis
Issued at 317 am edt Sat oct 21 2017
mild conditions will continue this weekend with highs in the mid
to upper 70s today and the low to mid 70s on Sunday. Clouds will
gradually be on the increase, with showers possible into northwest
indiana and southwest lower michigan later tonight into Sunday as
a cold front nears. Periods of rain and dropping temperatures will
become the story Monday into Tuesday as low pressure develops over
the great lakes region. Highs by Wednesday may struggle to reach
50 degrees behind this system.

Short term (today and tonight)
issued at 317 am edt Sat oct 21 2017
strengthening southwest flow in advance of a deep upper trough
ejecting east into the plains will continue to ensure unseasonably
mild temperatures today into tonight. Rain chances within leading
warm conveyor belt LLJ will remain well west of the area, though
cannot rule out some sprinkles light showers tonight into NW in sw
lower mi on eastward elevated fringe of deep moisture plume. High
clouds will be on the increase otherwise with highs well into the
70s again today.

Long term (Sunday through Friday)
issued at 317 am edt Sat oct 21 2017
pv lobe in the base of the aforementioned upper trough will briefly
be left behind into the lower ms valley by Sunday Sunday night while
northern stream energy breaks off through the western northern
great lakes. The result will be a weakening frontal zone east
into NW in SW lower mi Sunday and toward the i-69 corridor Sunday
night per latest model consensus. Moisture quality (with
precipitable water values pushing 1.6 inches within narrowing
theta-e axis) should be enough to squeeze out some light rain
(generally 0.05-0.30") along the frontal slope during this time.

Slower timing of the boundary will afford one more warm day with
highs into the low-mid 70s Sunday, warmest along east of i-69.

Deepening sfc low pressure will likely develop northeast along
the front Monday into early Tuesday. This will occur as an
impressive northern stream PV anomaly dives south into the
upper mid ms valley and picks up leftover southern stream wave
mentioned above. Strength track of said low will depend on the
degree of phasing, though expect a rather healthy deformation fgen
rain band will accompany the system regardless. The ECMWF gem
continues to be farther west with a soaking rain into at least
central eastern portions of the iwx cwa... While the 00z gfs
remained farther east drier save for NW oh. Bumped up QPF pops a
bit given the trends.

Windy, showery, and much cooler weather will become the story into
Tuesday and Wednesday as deep upper trough emerges over the region
with lake enhancement in strong CAA wing. Height rises ridging in
the wake of this trough should yield a slightly warmer mainly dry
second half of the week.

Aviation (for the 12z tafs through 12z Sunday morning)
issued at 634 am edt Sat oct 21 2017
vfr conditions expected with cirrus slowly thickening and
lowering, especially closer to ksbn later tonight as front draws
closer.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
